Cardiovascular drug use and differences in the incidence of cardiovascular mortality in elderly Serbian men.

Objective: To assess whether the difference in risk of cardiovascular mortality between urban and rural areas of Serbia could be explained by differences in the use of cardiovascular medication.

Methods: The Serbian cohorts of the Seven Countries Study, Velika Krsna (VK), Zrenjanin (ZR) and Belgrade (BG), were enrolled in 1962-1964 and were followed up for 25 years. The survivors of these cohorts were re-examined in 1987, 1988 and 1989, respectively.

Physical activity and dietary fiber determine population body fat levels: the Seven Countries Study.

Background: A global epidemic of obesity is developing. Current prevalence rates are about 20-25% in American adults and 15-20% in Europeans.

Objective: We investigated the association between population levels of physical activity, dietary fat, dietary fiber and indicators of body fat.

Saturated fat, vitamin C and smoking predict long-term population all-cause mortality rates in the Seven Countries Study.

Background: The Seven Countries Study has shown that population mortality rates for various chronic diseases are related to diet and smoking. This paper addresses the associations between diet, smoking and 25-year all-cause mortality.

Methods: Baseline surveys were carried out between 1958 and 1964 on 12,763 middle-aged men constituting 16 cohorts in seven countries.

Epidemiological study on risk factors and risk reducing measures for campylobacter infections in Dutch broiler flocks.

From September 1991 until August 1993 an epidemiological study involving 20 Dutch broiler farms was conducted to identify risk factors and risk reducing measures for campylobacter infections in broiler flocks. Campylobacter spp. were detected in 64 (57%) of the 112 broiler flocks and in 25 (63%) of the 40 broiler cycles examined.
